Lab: Introduction Purpose: To explore the relationship between temperature and the volume of gas. Question: What is the effect of a gas’ temperature on its volume? Hypothesis: If a fixed amount of gas is heated, then the volume will increase because the heat will cause the molecules of gas to move faster and further apart. Materials and Procedures: List of Materials: 600mL Beaker, Tongs, Tweezers, Thermometer, Cm Ruler, Hot Plate, Hot Pad, Ice, Oil Stopper, Rubber Band, 0.2 cm (about 0.08 in) Capillary Tube Variables: Temperature and Volume Procedure: Step 1 - Prepare the Capillary Tube a. Put the Oil Stopper into the Capillary Tube b. Connect the Capillary Tube to the ruler via a rubber band Step 2 - Prepare Materials for Measurement a. Put ice into a 600mL beaker, then fill beaker to 400mL b. Insert the Capillary Tube into beaker c. Wait 24 minutes for gas in the tube to reach the temperature of the bathwater d. Insert thermometer and record data Step 3 - Measuring with Hotter Temperatures a. Use tongs to place the beaker (with the tube and thermometer) onto the hot plate b. Turn on the hot plate and heat the water to the desired temperature c. Use tongs to remove the beaker from the hot plate d. Measure the height of the column of gas in the tube Step 4 - Repeat Steps 3 & 4 for the Following Temperatures (C) a. 20 Degrees b. 40 Degrees c. 60 Degrees d. 80 Degrees e. 100 Degrees Analysis and Conclusion Determine whether your data supported or refuted the hypothesis: The hypothesis being that the volume of gas will increase by the molecules moving faster when heated was supported by the data collected. While the temperature was increasing throughout the experiment, the volume of the gas also changed with it. Conclusion: When a fixed amount of gas is heated, the volume will also increase because the molecules of the gas are moving faster and further apart.
